Use VSPGENERATE. That's exactly what it was made for. Steve

Hello there,

Using vspgenerate isn't all that intuitive since it only creates vertices. Here's a macro that I've been able to run successfully. With a little luck, it might make getting started a wee bit simpler for you...

Regards,

Lars Ola

! Macro that extrudes fluid cells from a set of shells and vertices along a spline (in the direction of ascending spline vertex nos.)

! Input variables:

*set,csex,7 ! cylindrical coordinate system

*set,typs,4 ! cell type for baseline shells

*set,typc,15 ! cell type for fluid cells

*set,spid,4 ! extrusion spline ID

*set,edis,1.0 ! extrusion distance (% of spline)

*set,ncax,40 ! axial fluid cell count

csys,csex

! Disconnect baseline shells from model and extrude ncax layers of fluid cells along the spline over a distance of edis.
